Phys.org / Active supermassive black holes may help form massive planets
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...
Phys.org / Protein-like nanoparticles sort themselves inside growing crystals, enabling controlled release
The tiny bones in your fingers withstand countless taps and swipes thanks to a precise blend of materials. Flexible collagen fibers form the framework, reinforced by hard calcium phosphate hydroxyapatite crystals. This is ...
Phys.org / Firefighters battle second day of blaze on Greek island
Firefighters battled for a second day Sunday to contain a forest fire on the Greek Aegean island of Skyros, as the local mayor voiced hope it could soon be brought under control.
Medical Xpress / Lonely people can feel their heartbeat clearly like everyone else, but their brains respond differently
For a long time, psychologists have described loneliness as the discomfort that comes from wanting more social connection than we feel we have, but there is more nuance to loneliness. Scientists are increasingly finding that ...
Phys.org / Engineered microbe speeds CO₂ capture and recovers critical metals
A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements ...
Dialog / Bound gravitational waves inspired by photonic systems
When one mentions "waves," we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Medical Xpress / People carrying a rare gene variant have naturally low body fat, healthier livers and better blood sugar levels
There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study ...
Medical Xpress / Two devices in one: Metasurface could bring medical imaging to smaller sensors
Researchers have developed a technology for building more compact point-of-care medical imaging devices by creating a material that acts as two devices in one.
Phys.org / Mathematical model shows how birds create a synchronized dawn chorus
Every morning, groups of birds start singing and chirping around the same time, typically when the sun starts rising. While zoologists have been studying this collective bird behavior, called the dawn chorus, for decades, ...
Phys.org / Arctic fossil abandoned in 1948 proves to be record-size Triassic hunter
Nearly 80 years ago, a British expedition discovered the battered remains of a giant fossil on the peak of an Arctic island. Unable to take it with them, they snapped some pictures, took some bones and left the fossil to ...
Phys.org / Early snakes explored life underground, on land and at sea
Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
